MY SCIENCE TEACHER CAUGHT THE TABLE ON FIRE AND HES JUST STARING AT IT
HOW DO YOU FUCK UP READING CALIPERS THAT BADLY
Just how accurate are the memories that we know are true, that we believe in?
The brain abhors a vacuum. Under the best of observation conditions, the absolute best, we only detect, encode and store in our brains bits and pieces of the entire experience in front of us. When it’s important for us to recall what it was that we experienced, we have an incomplete [memory] store, and what happens?
Below awareness, without any kind of motivated processing, the brain fills in information that was not there, not originally stored, from inference, from speculation, from sources of information that came to you, as the observer, after the observation. But it happens without awareness such that you aren’t even cognizant of it occurring. It’s called ‘reconstructed memory.’
All our memories are reconstructed memories. They are the product of what we originally experienced and everything that’s happened afterwards. They’re dynamic. They’re malleable. They’re volatile. And as a result, we all need to remember that the accuracy of our memories is not measured in how vivid they are nor how certain you are that they’re correct.
Are your memories real .. or fake? Neurophysiologist Scott Fraser says you shouldn’t be so sure that what you remember is always what actually happened. Fraser researches how humans remember crimes, and in a powerful talk at TEDxUSC, he suggests that even close-up eyewitnesses to a crime can create “memories” they couldn’t have seen.

This is horrifying hahaha. (Via @amberbenson)
In which human reproduction seriously sounds like the Game of Thrones.
Newton’s third law says that forces come in equal and opposite pairs. This means that when air exerts lift on an airplane, the airplane also exerts a downward force on the air. This is clear in the image above, which shows a an A380 prototype launched through a wall of smoke. When the model passes, air is pushed downward. The finite size of the wings also generates dramatic wingtip vortices. The high pressure air on the underside of the wings tries to slip around the wingtip to the upper surface, where the local pressure is low. This generates the spiraling vortices, which can be a significant hazard to other nearby aircraft. They are also detrimental to the airplane’s lift because they reduce the downwash of air. Most commercial aircraft today mitigate these effects using winglets which weaken the vortices’ effects. (Image credit: Nat. Geo./BBC2)
are pringles flammable?
i guess they are
I admire tumblr’s dedication to science.
so much for the “if you can’t pronounce the ingredients you shouldn’t eat it” thing am i right?
EVERYTHING IS CHEMICALS
This. Is. AWESOME. THANK YOU!!!!
If anyone ever tells you that something you can’t pronounce or “sounds like a chemical” is bad for you, laugh in their face.
don’t forget that there’s enough potassium in 200 bananas to give you the same radiation dosage as a chest xray.
Circus Tree: Six individual sycamore trees were shaped, bent, and braided to form this.
how the hell do you bend and braid a tree
Actually pretty easy. Trees don’t reject tissue from other trees in the same family. You bend the tree to another tree when it is a sapling, scrape off the bark on both trees where they touch, add some damp sphagnum moss around them to keep everything slightly moist and bind them together.
Then wait a few years- The trees will have grown together.
You can use a similar technique to graft a lemon branch or a lime branch or even both- onto an orange tree and have one tree that has all three fruits.
As a biologist I can clearly state that plants are fucking weird and you should probably be slightly afraid of them.
On that note! At the university (UBC) located in town, the Agriculture students were told by their teacher that a tree flipped upside down would die. So they took an excavator and flipped the tree upside down. And it’s still growing. But the branches are now the roots, and the roots are now these super gnarly looking branches. Be afraid.
But Vi, how can you mention that and NOT post a picture? D:

The Super-Kamioka Neutrino Detection Experiment under Mount Kamioka near the city of Hida, Japan.
I assumed this was art until I read the caption
The shiny balls are very sensitive light detectors. The chamber is underground to cut out interference from any form of energy that can’t travel through rock. When it’s in use, the entire thing is filled to the top with water, and in pitch black darkness. Neutrinos can fly right through any kind of matter, even through the entire planet, but when they do, a small fraction of them collide with the matter and give off the tiniest flashes of light. When neutrinos from the sun (even at night!) or from particle accelerators in other countries collide with water molecules in this tank, the light detectors see it.
